Xbox 360 have transformed the Principality of Liechtenstein into a real-life replica of the Halo universe, to mark the launch of Halo 4.

The gaming giant took over some of the country’s most iconic landmarks, including a 13th century castle and a working mine, to create a sci-fi saga for fans from all over the world.

"Halo is a $3 billion blockbuster franchise which has shaped entertainment history and defined a generation of gamers,” said Chris Lewis from Microsoft.

"Halo launches have continually broken the mould and we are back with a colossal bang for Halo 4, transforming a country on the biggest scale imaginable," he added.

The game is out on November 6.
